To a/ZZ whom t may concern.-

Be it known that I, CHARLES A. PARKS, a citizen ofthe United States, residin at Baltimore city, and State of Maryland, ave invented certain new and useful Improvements in Flushing-Valves, of which the following is a specification.

Myinvention relates to 'an improvement in flushing valves as pertaining to .closets and the like, the object being `to dispense with the tank which usually forms a part of an apparatus of this character, and, at the same time, I- haveprovided a device in,

which the body' of water used in iiushing the closet can be regulated to such an extent and 'in such a manner that a single device can be used to supply a seriesof closets as eiiectively as applied to a single closet.

In the construction of my device the durability, cost of manufacture, as well as the effectiveness of purpose, have not been lost f sight of, and with these objects in view my invention consists certain other new and novel features of construction and combinal va ve stem 16 by means oft e screw 19; 20v

isa lcollariitted 'seated upon the shoulder 21 and the collar is a packing 22;

tions of parts, which will be hereinafter described and pointed out in the claims.

I do hereby declare the followingto be a full, clear and exact'description ofthe device,

as invented by me, such as willenable others skilled inthe art, to which it appertains to make and use. the same.

The accompanying drawing shows a ver,- tical sectional view of my invention.

A isa ca'st body portion; B, C, D andE are reservoir chambers'within the casting; 1 is the inlet, inwardly threaded at2; 3 is the outlet exeriorly threaded at 4; 5 4is a taperedneedle valve stem threaded at 6, and' adapted to screw within the threaded bored portion 7, with. the tapered point within the opening 8, the exterior end 9 Vof the stem is made square or hexagon for the purpose of being engaged by a wrench or other suitable tool, whereby the needle valve is regulated l() is a packing cap,and 11 is' a packing; 12 is a cylinder, threaded at 13, and provided with a shoulder 14; within the cylinder are 'rovided the circular openings 15; 16 1s a valve-stem; 17 is a stem disk;

18 is a leather cu washer secured on the u per end of the around the valve stem and shoulder 21; between the l secured on the lower end of the valve stem 16,. bymeans of the `screw 23, is a valve disk -24 and a fiber washer 25; around the lower end portion'of the valve stem 16 between the'collar 20 and the valve disk 24'is secured a spiral spring .26, adapted 'to seat vthe valve so formed, which we will designate F, on the valve seat 2-7, under the conditions to be hereinafter explained; 28 is a packing nut into which is secured any suitablepacking (not shown) at 29; 30 is a bonnet provided with a shoulder 3 1, threaded at 32, and adaptedto be screwed within a boredo ening' inthe top or the'jcasting A, whic is the bonnet 30V and thecasting A, isz laced a packing 34; in a similar manner is t e cylinder 12 secured Vwithinthe op osite side ofthe casting A, and provided wit a similarpackder 12 and the casting A; 35 is a valve stem, 36 is avalve disk, -37' a iiber disk secured "on the lower end -of the valveL stem 35, by means of the screw 38;.v secured around-.the lower end portion 'of the valve stem 3.5 and between the bonnet 30 and the valvedisk 3'6. is secured a spiral spring39 adapted to seat the valve G so 'formed on the valve ,'Jeat 40 in is a vertical arm secured to the 'casting A-by means of the ,screw 42; 43 is. a cross arm pivot-ally secured on the endof the vertical arm 41 near its end portion at 44, and is similarly secured to the upper end ofthe valve stem 35 on the end thereofat 45; within they free end of the arm 43 is secured a chain46 or ating the device in a manner now about vto be explained:

into the chamber B, theneedle valvegis adjusted to permit the water to Ii'ow into chamber C, thence through the openings v15 in the ,cylinder it flows into chamber D; by reason of the pressure on the water aftei'ichamber becomes filled the chamber E also becomes illed. By reason of the pressure of the wasure around the valvel stem's the-respective valves G and F are firmly closed on their ref spective valve seats; by pulling the chain '46',

ing 34, between the shoulder 14 of the cylin the manner to be hereinafter explained; 41

My device isoperated as.gfollowswaterun"+ der pressure enters through the y[opening 1f attached to the end of the lever`43 the valve .threaded at 33; between the shoulder 31 .of

. .290 other suitable means whereby the valve stem 35' is made to reciprocate thereby opere terwithin the chambers and the spring presnos -likewise pass therefrom, through the outlet stem 35 within the chamber D is raised, l thereby liftingthe valve `Gr from its seat per- ,l niittingthewater within. chamber D to pass out .through the outlet the releasing oi this pressure also allows the water in the chamers-C and E to flow into chamber I). and

3;.When the'pressure is released the pressure 0f the water in chamber B is such as to raise the valve F and cause the water to 'llow directly into and out of the outlet The water will continue to flow in thisdirection l and channel until the pressure-is again re- 'l stored, which is accomplished in the following manner: When the' ,ham i6 is released the Valve G by reason of `he spring pressure l will close; the spring on the valve F while not being made strong "enough to automatically i close the Valve F against the pressure, is, l however, of sulicient strength to gradually l close thevalveby reason of the pressure il Within the chamber B,'being lessened by real son of the needle valve, which, of course, l must be regulated 'according to the outside pressure and which relieves the pressure l Within the chamber B, by permitting the wa ter to fiow within chambers C, D and E, until' j they become iilled gradually increasing the i pressure on the Valves, thereby gradually overcoming the pressure in chamber B, asl sistedby the springs within the valves thereby closing the Valves and shutting oil the'ilow of water until the chain is again pulled when the same action just described will be repeated.

As explanatory ot' the terms used in the following claims, I desire to call attention 'to the fact that the portion of the interior oi' the casing between needle inlet port 8 and valve port constitutes a reservoir passageway, and that the .chamber B may be looked upon as the iushing passageway-1 i In further explanation of the operation o'i' my device, I wish also call attention to the fact that the opening in shoulder 21, which constitutes part of the bottom wall of the reservoir passageway, is proportioned to permit the insertion and removal therethrough of the Valve head F. The collar 20 is an embodiment of a member iorreceiving and guiding the Valve stein' 16; and I regard the passageway, so as to close the opening therei 1n, by means of the threaded cylinderE as of described without departing l l i l l l l 1 l l l l l clamping of this collar against the wall oi the l distinct novelty` and material importance. l Slight changes might be resorted to in the form and arrangement ofthe several parts from the spirit sageway, a cylinder within the and scope of my invention, hence I do `not wish to limit myself to the exact construction as herein set forth, but,

Having described my invention what I claim as new anddesi're to secure by Letters Patent, is:

1. In a iiush valve, the combination with a casing having an inlet and an outlet, a reservoir passageway communicating by a Valve port with said outlet and by restricted opening with said inlet, and a flushing passageway communicating with the inlet and by a Valve port with the outlet, o'l" amanually operated Valve normally closing the valve port of the reservoir passageway, a reciprocating valve member comprising a Valve head normally l closing the Valve port ol the flushing passagef way, a stem passing through an opening in the wall of the reservoir"passageiifftjif1`sri-id`-- l opening being proportioned to permit the i passage therethrough ot said Valve head, and

a piston on the stemw'ithin the reservoir pasreservoir passa geway -within which said piston is received and guided, and a collar loosely but closely encircling said valve stem and closing the opening in the wall of the reservoir passage way,

2. In a llush Valve., the combination with a casing having an inlet and an outlet, a reservoir passage-wry communicating by a valve port with said outlet and by restricted open ing with said inlet, and a flushing passageway communicating with the inlet and by a valve port with the outlet, of a manually operated valve normally closingfthe valve port of the reservoir passage 'n.y, a reciprocating valve member comprising valve head normally closing the valve port of the liushing passageway, a tem passing through an opening in the wall of the reservoir passageway, said opening being proportioned to permit the `passage therethrough of said valve head, and
